difficult reading of received Press Gmail messages

Hello. I am using Onyx Note3 10.3 which is very useful for me because e-Ink suppresses the 70 p/s frame rate .

Nevertheless, I don't succeed to obtain correctly readable functioning for reading the Gmail messages  that I receive daily for my professional Press, i;e; Bibliography.

1. I have organized contrast and so-on so as to read perfectly the title of each message received. It works well.

2. In addition, for each  review, I have also organized  all parameters so as to read perfectly each article one by one. It works well.

3. On the other hand, "between 1 and 2", aperture of one "message" that is corresponding to one Review issue, the list of different titles and notes contained in this issue is unreadable because being written in grey on a black support: that means obviously that the parameters  I used for  the 1 and/or  2 steps are not OK for 3.

-----> I whether if there is a solution OR if I should  wait for  a probable next upcoming 10.3 Kaleido plus models, that would be too expansive for me for now.

I Thank you by advance for your answer. Cl.Moraine
